To all; Lo/zbmifinia-y (,ogwemf Be it known that I, viimrnno Lniioi, engineerya' citizen of German Republic, 1'S]Ci ing at Frankfort-on-tlie Main, in the county ofliessen-Nassau, State ofPrussia (whose i ice' address is-Frankfort-on-the Main, iz-erlandstrassc 142), have invented certain new anduseful Improvements in Flow- Oil and Shut Off Devices for'Toilet Cups,

for which applications jforpatcntswere filed in {Jeimiiny'- the 4th day of l'kugust, 1917 (D. P. No. 314,306) and the 18th day of September, 1920(1). R. P. No, 342,597) and I do hereby declare the following to be a full, Cl6d1,- and exact description of. the-invention,

such as will enable otherssl rilled iiifthe art to which it appertainsto make and use the same. v r r v,

This invention relates to an improved flow-off and shut-off device for toiletcups. having, over the known art, the advantages hereinafter mentioned.

The accompanying drawing illustrates the subjectmatter of the present invention;

Fig. 1 is a perpendicular section through part of the toilet-cup embodying the flow-off and shut-off device,

Fi 2'is across section on .the line A- B.

Fig. 3 is a cross secti'on on the line C- D ofFig. 1, v 7

Fig. at is a perpendicular section through the shut-off device in connection with a. eylindrical strainer,

Figs. 5 and 6 show -two other forms of strainer. g 3 g 1 designatesa toilet-cup having at-its rear wall a perpendicular cylindrical chamber 2 .which ismade in one piece with said cup.

The lower end of said chamber 2 is widened or enlarged and'fitted, from below and outwards, with a metallic shell 4 having a tightening washer 5' toward said" chamber. Said shell 4: has a lateral opening 9 which coincides with the outlet 3 of the cup 1 located at the lowermost point thereof and leading from said cup into said chamber 2 or said shell 41- respectively. In said shell 4 a tightly closing cylindrical shut-off body IO-is located and provided with an opening 11 corresponding to the opening 9 in said shell 4.- Said shut-off body 10 carries an'upwardly extending rod 12.

In the example illustrated, the upper end. of said rod 12 projecting beyond the usual cover-plate otsaid cup 1 is supposed to ,be

provided-z with an integral hand-levei (iiot shown) by means of which theshu't off body 10 beit-urned'onits' own axis for I80 andthus" into the posit-ion for closing the outlet '3.

I he shutsoflf b0dy 1 O inayalso be so adjust'ed that its plain wall closes the opening 9 in the shell 4. it being secured against turn ing 'by any suitable" m ans. iUfponi t-heshutoff bodyflObei-ng then lifted by" neans 'of I,

its rod I2,'the outlet' 3 is=opened.'W'

' The-improved". shut oifqd'evice has" the fol lowing advantages:

I 1. ir -by" theinsertion of the metallic shell into the cup 1 from below'-a sim-pleand'easy accessibility of T i, the shut-off device is at-' v.tained, while after removal of the shut-off body 10 and of afiat strainer 13 arranged therein an easy cleaning of the. chamber 2 is possible;

2. the metallic 'parts (shell 4 and shut-off body 10) can ,be keptlas low as possible, j

which allows also a good and easy cleaning;

3; with one andjthe same design-ofcupl the adoption of a turnableor'ofa liftable the manufacture and storage;

Instead of a fiat strainer may have the shape shown in Figs. 5 0r 6.

eign mat'ters only canflow-off- The -cham-.

the'cylindrical strainer 23 shown in Fig. 4',

a-strainer ofpthe shape shown in Figs. 5 or. 6,' that is with closed vperforated top and-bot tom or with-closed perforated bottom only, is employed, the chamber 2 is also secured I 13' shown in: Fig- 1, according to Fig. 4 a perforated cylinder 23 may be employed, which, besides,

shut-off device ispossiblefwhic h simplifies 8s 1 Said strainer 23 secures also the outlet 3 in such a way that liquid and very small forher 2remains always free." If, insteadof' through a straining device The latter acts, however, in this case, as a bye-strainer only owing to the cylindrical surfaces of the strainer retaining large- 1 foreign. matters, which might passjthrough the outlet 3 and else obturate the chamber 2.

' "What I claim, is i In combination, a' toilet-cup at rear walllprovided with an overflow andoutlet ioo let, a metallic shell inserted from belowqinto said enlargement, a tightly closing shut-off body in said shell adapted'to close the outlet chamber having a'lower enlargement therein and at its lowermost point with an outin said cup, a strainer in said shut-ofi' body,

and means to operate said shut-off body,

said shell and shut-off body being of low height and extending but little above said outlet substantially as and for the purpose" set forth.

In combination, a toilet-cup at its rear 7 body in said shell adapted to close the out let in said cup, a cylindrical strainer in said shut-0E body, and means to operate said shutoif body, said shell and shutofi body being of low height and extending but little above said outlet, substantiallyas and for the purpose set, forth, v

3. In combination, a tollet-cup at its rear wall provided with an overflow and outlet chamber having a lower enlargement therein and at its lowermost point with an outlet, a metallic shell inserted from below into said enlargement, a tightly closing shut-off body:

in said shell adapted to close the outletm said cup,-a cylindrical strainer in said shutoff body having a closed perforated bottom, and'means tooperate said shut-off body, said shell and shut-off body being of low height'and extending but little abovesaid outlet, substantially as and for the purpose set forth. 7 V I 4. In combination, a toilet-cup at its rear wall provided'withan overflow and outlet chamber having a lower enlargement therein and at its lowermost point with an outlet, a metallic shell inserted from below into said enlargement, a tightly closing shutoff body in said shell adapted toclose the out let in said cup, a cylindrical strainervinlsaid shutoff body" having a closed perforated bottom and top, and means to operate said shut-off body, said shell and. shutoff body being of low height and extending but little above said outlet, substantially as andfor the purpose set forth. a In testimony whereof I afiix my signature, in presence of two witnesses.
